haha I actually did try the paperclip on the car side of the socket. It didn't really want to fit up into the 2 holes very well....but it didn't turn off the warning light (left the car on ignition for a bit to see if it would go out). May need a thinner wire.

I examined the old sensor I took off the front and it didn't look rubbed at all (front hitting the rotor)

I'll also be jacking up the right side rear and take a look at that sensor. heard its a bit more of a pain to change. The front only cost me $10 for an aftermarket sensor so not bad. 2014 FF Autobiography 5.0 SC
